User interface view
Parameter
None
Description
Using the shell command, you can enable terminal services on a user interface.
Using the undo shell command, you can remove the current setting.
By default, the terminal services are enabled on all the user interfaces.
Some constraints are put on the undo shell command. First, CON does not
support this command. Second, if there is only AUX but no CON on a router (AUX
and CON shares the same port), the AUX will not support this command as well.
These constraints do not apply to other types of user interfaces.
Example
Disable terminal services on the virtual terminals (VTYs) 0 to 4.
[3Com] user-interface vty 0 4
